When will I ovulate?!

I got off BC pill in September and immediately had a period. Then in December I hadn’t had a period since and wasn’t pregnant so my OBGYN called me in provera. I took that for 10 days and still no period. Then about a week after I ran out of provera pills I started and had a normal (for me) 6 day long period. Now according to Glow I’m in my green window. I have taken opk the past 3 days and all have been medium dark lines. Am I going to ovulate soon? Or is there anyway to know besides taking more opk? Sorry if this sounds silly but this is my first time TTC. Thanks!
